Statement 1: AgI is less soluble in water than AgF due to more polarization of I− ion in comparison to F− ion.
Statement 2: The melting point of BaCl2 is higher than the melting point of BeCl2 due to the greater ionic nature of BaCl2.
Statement 3: The order of hydrated radii is: Al3+(aq)>Mg2+(aq)>Na+(aq)
